A method for depositing samples, in which at least one sample () is arranged on a substrate (), comprises the following steps: positioning a sample dispenser () above the substrate (), and actuating the sample dispenser () so that the sample () is moved from the sample dispenser () along a trajectory () to a predefined deposition position () on the substrate (), wherein at least part of the trajectory () is shielded against electrical interference fields. Also described is a substrate () for receiving samples (), comprising a substrate body (), on the surface of which at least one deposition position () is provided, and a shielding electrode (), which is designed so as to electrostatically shield the space above the at least one deposition position () against electrical interference fields.
